I am using custom camera in my application this works fine in jelly bean. Now after this Samsung Galaxy Tab OS update the custom camera is broken. I got this report from one of my friend i didn't saw that tablet. And i got crash report form Carshylytics.
My log report:

And this error line is
public MediaRecorder mrec = new MediaRecorder();
Why it is happen have any idea? How can i solve this issue. I hope the camera code is not needed. But anyone want to see the code i can post here.

I got the error Because of Video sizes are not set. I solve this
int width = 320;
int height = 240;
try {
//get the available sizes of the video
List<Size> tmpList = getSupportedVideoSizes();
final List<Size> sizeList = new Vector<Size>();
// compare the apsect ratio of the candidate sizes against the
// real ratio
Double aspectRatio = (Double.valueOf(getWindowManager()
.getDefaultDisplay().getHeight()) / getWindowManager()
.getDefaultDisplay().getWidth());
for (int i = tmpList.size() - 1; i > 0; i--) {
Double tmpRatio = Double.valueOf(tmpList.get(i).height)
/ tmpList.get(i).width;
if (Math.abs(aspectRatio - tmpRatio) < .15) {
width = tmpList.get(i).width;
height = tmpList.get(i).height;
sizeList.add(tmpList.get(i));
}
}
if (EnableLog.LOG_TAG) {
Log.e("tmpList", tmpList + "*");
}
} catch (Exception e) {
e.printStackTrace();
}
mrec.setVideoSize(width, height);
public List<Size> getSupportedVideoSizes() {
if (params.getSupportedVideoSizes() != null) {
return params.getSupportedVideoSizes();
} else {
// Video sizes may be null, which indicates that all the supported
// preview sizes are supported for video recording.
return params.getSupportedPreviewSizes();
}
}
